FAST (Faceted Application of Subject Terminology) ALA Annual 2015 OCLC Research in Brief Roy Tennant Senior Program Officer OCLC Research Explores challenges facing libraries and archives in a rapidly changing information technology environment Three primary modes of activity: Community research & development Advanced development (data mining, prototyping) Member/Partner engagement
OCLC Research Library Partnership Work is openly available, e.g., Reports Experimental services THEMES New Report: Stewardship of the Evolving Scholarly Record The scholarly record is evolving, so stewardship models for scholarly record are changing too Conscious coordination
key to securing future of scholarly record oc.lc/esr-stewardship Library Linked Data in the Cloud Just published Offers insights gained from OCLCs innovative work with linked data Main sections:
Library Standards and the Semantic Web Modeling Library Authority Files Modeling and Discovering Creative Works Entity Identification Through Text Mining The Library Linked Data Cloud Technical but approachable Anyone with a modest background in metadata can read & understand it ALA Annual 2015 Wikipedia & Libraries Increasing Library Visibility

Consulting Software Engineer The Knowledge Graph A Google blog post from 2012 describes the Knowledge Graph that supports searching for the things, people and places that Google knows about and suggestions for relevant related things. The Graph powers the Google Knowledge Panel in search results
The Google Knowledge Vault A series of recent Google Research papers describe the use of probabilistic models and machine learning to assess the truth of statements made by multiple sources. Li, X., Dong, X. L., Lyons, K., Meng, W., Srivastava, D. (2013). Truth Finding on the Deep Web: Is the Problem Solved? Dong, X. L., Gabrilovich, E., Heitz, G., Horn, W., Murphy, K., Sun, S., Zhang, W. (2013). From Data Fusion to Knowledge Fusion. Dong, X.

Dong, X. L., Gabrilovich, E., Murphy, K. Dang, V., Horn, W., & Zhang, W. (2015). Knowledge-Based Trust: Estimating the Trustworthiness of Web Sources A Knowledge Vault for Libraries? OCLC research scientists and software engineers are prototyping a similar model for bibliographic and authority data sources, in combination with user-contributed content and Linked Data from other providers, to evaluate a knowledge vault for statements about entities and their relationships, including people, groups, places, events, concepts, and works. Library data sources
WorldCat thousands of libraries, museums and archives contribute to the aggregation. OCLC adds FRBR clustering, algorithmically-deduced connections of strings to Linked Data identifiers, and new entities. VIAF 30 or more authority systems contribute, and OCLC merges and links records into new VIAF clusters. FAST OCLC transforms Library of Congress subject headings into a new controlled vocabulary, friendly to faceted navigation. Knowledge Vault data flow Enhanced WorldCat
Extractor VIAF Extractor FAST Data Sources Knowledge Triples
The EntityJS Research Project Get some real-life RDF experience, test entity refinement and editing, and push triples back to the knowledge vault. Testing with a subset of Knowledge Just the ArchiveGrid WorldCat MARC records WorldCat VIAF FAST ArchiveGrid
Knowledge Vault Search across entities Show related entities Show related entities Get more relationships from Wikidata EntityJS users can identify matching entities EntityJS users can identify matching entities
As the EntityJS research project continues We will explore other ways to edit and refine entity data and experiment with using the knowledge vault to support data visualizations Keeping up with EntityJS Track initial progress reports on the OCLC Research blog at hangingtogether.org. Well provide project details on the OCLC Research website soon. Questions or comments? Bruce Washburn ([email protected]) or Jeff Mixter ([email protected])

Developed to meet a need for a general subject vocabulary that is easy to learn, apply, and control Modern design All headings established in authority file Persistent identifiers for all headings Obsolete headings deprecated not deleted Authority file structure facilitates application and automated maintenance of headings Faceted-navigation friendly
